Dry Mouth even with mouth tape

[SligoReef]

I use a Resmed 10 Airsense with a nose cushion type mask. I also tape my mouth to prevent mouth breathing. The tape I use (3m blue painters tape) works very well and doesn't come off except on very rare occasions. I also use the humidifier with with the setting on 3.

Over the last couple of months, despite the mouth tape, I have awoken in the middle of the night with a dry to very dry mouth. Don't understand how it can be happening since I tape up my mouth. Dry mouth is not a problem during the day so I doubt it is a medication causing it.

Anyone have a clue to why this would be happening?

I've been having the same issue and can't figure it out either

Try Xylimelts.

The tape doesn't have to "come off" for that to happen. All it needs it a little looseness somewhere along the strip, and air will start blowing out and drying your mouth.
When you wake up with a dry mouth, and you think the tape is stuck firmly, try blowing air out through your mouth. Is nothing escaping?

I use mouth tape too, but sometimes air leaks out anyway. I don't know how to overcome the leaking, but most nights I don't show air leaking. My ahi is usually less than 1, so I don't worry about it too much.

Struggling with the same issue tonight. The cheeks expand and the mouth dries out with the circulating air, no need for a tape leak.

I'm going to try a different thumidity level, maybe auto setting for a higher humidity level, so it won't dry out as much. And get another cervical collar to help keep the jaw closed a bit more.

With more air conditioning use, this dry mouth has become a bit of a problem this hot summer. Hard to tell what night it will happen, though.

I had picked up a humidifier, too, but at 50% ambient humidity I probably shouldn't need one.
